    build: no need to chmod the test file which is already executable.
    
    Also when working on out-of-tree builds, it would not find the file
    anyway and we get this output:
    
    > chmod: cannot access 'test-installer-langs.sh': No such file or directory
    
    Though this was not breaking the tests, it has clearly been useless
    until we see this one today.
